Ok, yeah, I'm a noob; so please keep your suggestions as friendly as possible.
Here's the situation: I've recently got a new desktop PC; and for a while I used the old monitor we had. The game ran perfectly. Later, we got a new monitor, a 22''; but since, every single server connection fails. I'm not sure what's going on; and even stranger, a small netbook PC can even run it and connect just fine; but the desktop PC can't, for some reason.
Has anyone had the same problem before? Could it be a settings problem? What is it if not?
Thanks in advance from the help.
